Abstract
Epidemiological studies have illustrated convincingly that fat distribution is associated with cardiometabolic risk. Fat deposition preferentially in the lower body, commonly seen in premenopausal women, is associated with lower risk, while central obesity in men and postmenopausal women is associated with higher risk. Studies of the physiology and the tissue and cellular characteristics of different adipose tissue depots, visceral and abdominal, gluteal, and femoral subcutaneous, corroborate this idea. In this report, we chose to focus on interventions-surgical, hormonal, lifestyle, and pharmacological-that directly or indirectly affect fat distribution, seeking further evidence for its pathophysiological significance.

Abstract
Various therapeutic options are available for treatment of recalcitrant plantar fasciitis. Studies using TOPAZ coblation (ArthroCare, Sunnyvale, CA) have had good early results. The current coblation technique involves a surgical incision or breach of the highly specialized plantar fat pad, which can be associated with risks. We describe a novel technique of ultrasound-guided percutaneous coblation with a lateral heel approach. Advantages include precise targeting of the plantar fascia by direct dynamic visualization of the coblation tip, a true percutaneous approach with a needle skin puncture (<5 mm), and preservation of the plantar fat pad by using a lateral heel approach.

Abstract
OBJECTIVE To investigate a simple, minimally invasive and effective operative method for the facial rejuvenation in the upper eyelid and midface region. METHODS Blepharoplasty was combined with suspending orbicularis oculi muscle flap and fixing it on the periosteum underneath the eyebrow through eyebrow incision. Meanwhile, for midface rejuvenation, inferior palpebral margin incision was performed and prezygomatic interspace was separated completely under the orbicularis oculi muscle. The under-eye puffiness and tear trough deformity were corrected through releasing orbital fat, reposition and fastening orbital septum, and transposition of orbicularis oculi muscle flap. And the deep sulci nasolabialis and cheek anetoderma were relieved by dual lifting of malar fat pad and orbicularis oculi muscle flap. Follow-up was taken at the 1 week,3 months,6 months,1 year,2years and 3 years after operation. Each case was evaluated with postoperative effect, reprocessing time and postoperative complications and underwent photography. RESULTS From Feb.2010 to Oct.2014,190 patients (9 male,181 female, an average age of 49.03 ± 5.67 years) underwent this operation. Obvious improvement on the upper eyelid and midface region was achieved in all the patients after operation without serious or irreversible complication CONCLUSIONS Combining eyebrow and inferior palpebral margin incision, through suspending the malar fat pad and orbicularis oculi muscle flap at the same time, as a simple, minimally invasive and reliable method, can strengthen the effect of the facial rejuvenation in the upper eyelid and midface region markedly.

Abstract
Bronchial stump fistula is a post-operative complication with poor outcome after pulmonary lobectomy. In order to prevent this complication, the bronchial stump is covered with pericardial fat tissue in our hospital. The case was 58 year old male who received adjuvant chemotherapy after sigmoidectomy for sigmoid colon cancer. As he developed multiple pulmonary metastases, 48 courses of chemotherapy were performed. The lesions had been localized at the right lower lobe, and neither increase in the size of these lesions nor development of other lesions were observed. Hence, an operation was performed. After right lower lobectomy, the bronchial stump was covered with the pericardial fat tissue. Three months after the operation, he developed pneumothorax, and bubbles were detected inside the fat. The pneumothorax was cured conservatively, and the bubbles disappeared spontaneously after 10 months. It is rare that the patient with bubbles in the covering tissue observed for a long time is cured conservatively, suggesting the significance of the stump pad.

Abstract
OBJECTIVE To discuss the rhytidectomy technical improvements and clinical efficacy and safety, using the purse-string imbrication suture in midface and lower face lift. METHODS The absorbable purse-string suture was used in a pure antigravitational direction for correction of the aging middle and lower parts of the face. The volume of cheeks and jowls was repositioned in a cranial direction with a first, slightly oblique purse-string suture on SMAS. To correct the nasolabial fold, the face-lift was performed by adding a second malar vertical purse-string suture between the paracantbal area and the malar fat pad. RESULTS From July 2009 to May 2014,52 patients underwent this technique for facial rejuvenation with obvious effect and high satisfactory rate. There was only two minor complication of hematoma. CONCLUSIONS The Purse-string imbrication suture in the rhytidectomy produces a natural face lifting through a better correction of the sagging tissue and restoration of the volume of the face. This is a simple technique with good results, short down-time, and high patient satisfactory rate.

Abstract
BACKGROUND The study was conducted to clarify the presence or absence of fronto-temporal branches (FTB) of the facial nerve within the interfascial (between the superficial and deep leaflet of the temporalis fascia) fat pad. METHODS Eight formalin-fixed cadaveric heads (16 sides) were used in the study. The course of the facial nerve and the FTB was dissected in its individual tissue planes and followed from the stylomastoid foramen to the frontal region. RESULTS In the fronto-temporal region, above the zygomatic arch, FTB gives several small twigs running anteriorly in the fat pad above the superficial temporalis fascia and a branch within the temporo-parietal fascia (TPF) to the muscles of the forehead. There were no twigs of the FTB within the interfascial fat pad. CONCLUSIONS No branches of the FTB are found in the interfascial (between the superficial and deep leaflet of the temporalis fascia) fat pad. The interfascial dissection can be safely performed without risk of injury to the FTB and potential subsequent frontalis palsy.

Abstract
INTRODUCTION Many recent studies concerning autologous fat grafting in the eyelids have been published, mostly consisting of case reports and retrospective case series. However, no study on the overall complication or satisfaction rate associated with the various grafting techniques exists. We performed a comprehensive literature review to determine the outcomes and complications of eyelid fat grafting, as well as patient satisfaction. METHODS A systematic review of the literature using the PRISMA criteria was conducted. This protocol was registered at the Prospective Register of Systematic Reviews at the National Institute for Health Research. RESULTS Sixteen studies, representing 1,159 patients and published between June 2004 and December 2014, were included. Satisfactory results, judged by clinical examination, were observed in all studies. Few postoperative complications were reported. CONCLUSIONS We demonstrated that the procedures were easy to perform, and achieved satisfactory and sustainable results with few complications in both reconstructive and cosmetic surgery. However, a wide disparity exists in the various fat harvesting, fat purification, and reinjection techniques. Further studies are required to assess the long-term outcomes. Our conclusions should be accepted cautiously due to the small number of articles and the lack of evidence in published studies.

Abstract
Fat-forming solitary fibrous tumor (SFT) is a rare soft tissue tumor. Herein, we reported a 30-year-old woman was found to have a solid mass measuring 60×45 mm in the right kidney on an abdominal computed tomography scan. The tumor was well-circumscribed and composed of cellular nodules with the classic SFT admixed with clusters and lobules of mature adipocytes. Immunohistochemistry staining showed that the tumor cells were diffusely and strongly positive for CD34 and Bcl-2, focally and weakly positive for CD99 and EMA. Mature adipocytes were positive for S-100 protein. Ki-67 expression was found in approximately 2% of tumor cells. However, tumor cells were negative for cytokeratin, S-100 protein, HMB-45, Melan-A, SMA, and CD117. We made the pathological diagnosis of fat-forming SFT of the right kidney. The differential diagnosis includes angiomyolipoma, liposarcoma, spindle cell lipoma, sarcomatoid renal cell carcinoma, synovial sarcoma, and gastrointestinal stromal tumor. The patient was alive and well without evidence of recurrence or metastasis at 19 months after tumor resection.

Abstract
AIMS To describe the results of orbital decompression in patients with spontaneous globe luxations and to evaluate predisposing factors for this condition. METHODS The clinical records of patients who underwent orbital decompression for the treatment of spontaneous globe luxations between 2010 and 2013 were reviewed. Data collected were age, gender, predisposing factors, preoperative and postoperative exophthalmometry, duration of follow-up, presence of diplopia before and after surgery and intra- and postoperative complications. RESULTS Seven patients underwent orbital decompression after spontaneous globe luxation during the study period. Six patients underwent bilateral decompression. Two patients underwent a three-wall decompression, four of them medial and lateral decompression and one patient medial decompression. The predisposing factors for globe luxation were Graves' orbitopathy, malar hypoplasia, high myopia, floppy eyelid syndrome and orbital fat hypertrophy in the context of obesity. After orbital decompression, none of the patients reported new globe luxations. No intraoperative complications were observed. None of the patients developed de novo diplopia. DISCUSSION Orbital decompression is an effective method for the prevention of new episodes in patients with spontaneous globe luxations. It has good aesthetic and functional results and addresses the exophthalmos present in most cases.

Abstract
Lumbar disc herniation (LDH) is the most common cause of radiculopathy, whose pathological entity underlying nerve root compression is usually on the same side as the symptoms. However, LDH causing contralateral radiculopathy are sometimes encountered by pain physicians. There have been tremendous developments in the treatment options for LDH; the situation of LDH causing contralateral radiculopathy is indeed a dilemma for some pain physicians. We will report a case of a patient with a L4-5 disc herniation whose left herniated disc caused radiculopathy on the right side. After a percutaneous lumbar endoscopic discectomy via the side ipsilateral to the symptomatic side, this case obtained a significant symptom remission. The migrated epidural fat is discussed as a cause of associated contralateral neurological deficit. Only via a surgical approach ipsilateral to the herniated side, could there be a clinical improvement postoperatively.

Abstract
Skin surface irregularity is the most common side effect after liposuction. To reduce this, it is necessary to devise a systematic method to provide structural composition details of skin layers, such as fat thickness and fat boundary tilt angle, for the plastic surgeon. Several commercial portable devices are available to measure skin layer information, working on the principle of a near-infrared technique using the light penetration properties of tissue in optical windows. However, these can only measure general fat thickness and not the structural compositions of skin layers with irregularities. Therefore, our goal in this paper is to propose a method to estimate the structural compositions of skin layers by analyzing and validating the relationship between light distribution and structural composition from simulation data based on specific structural conditions.

Abstract
Autologous fat injection is a common aesthetic procedure for soft-tissue augmentation of the face. Although this procedure is generally regarded as safe, several patients have experienced acute visual loss or cerebral infarction after these injections. We describe a case of internal and external carotid artery fat embolism that occurred following injection of autologous fat into the face. It appeared that the injected fat entered a branch of the left external carotid artery and that the embolus likely migrated into the left internal carotid artery and distally into the left ophthalmic artery, left anterior artery, and middle cerebral artery.

Abstract
UNLABELLED OBJECTIVE To investigate an operative method of combined resection of preseptal fat: and partial retro-orbicularis oculus fat (ROOF) for correction of upper eyelid heaviness, and evaluate the efficacy and safety of the method. METHODS Preseptal fat lies widely under the orbicularis oculi in the upper eyelid, and retro-orbicularis oculus fat (ROOF) lies in the lateral supraorbital area. Combined resection of preseptal fat and partial ROOF was performed in patients selected by examination. The efficacy and safety were evaluated by follow-up study. RESULTS From May 2011 to July 2013, 38 selected patients received the treatment with 3 months to 28 months follow up. The heaviness of upper eyelid improved in all cases. One patient developed postoperative hematoma, and another patient had a transient numbness over the lateral upper brow region. 37 patients were satisfied with the result. CONCLUSIONS Combined resection of preseptal fat and partial ROOF was effective in reducing the heaviness of upper eyelid, without major complications. The operative method should be an important adjunct for selected patients undergoing blepharoplasty.

Abstract
BACKGROUND Plastic surgeons are exploring novel techniques for augmentation gluteoplasty as the demand for this procedure increases annually in the United States. OBJECTIVES The authors retrospectively reviewed a series of lower abdominal dermal-fat graft augmentation gluteoplasties to validate the procedure. METHODS Nine consecutive patients underwent abdominoplasty or torsoplasty in which 2 oval dermal-fat grafts were excised, de-epithelialized, and then implanted into subfascial gluteal pockets for augmentation. All operations were independently conducted by 1 of 2 surgeons at facilities in Maryland and New Jersey. RESULTS The mean age of the 9 female patients was 46 years. The mean dermal-graft size was 188 cm(2), and the mean graft weight was 288 g. One graft became infected and required excision 39 days after the procedure. There were no other complications. All surviving grafts provided a substantial increase in posterior projection and long-lasting gluteal volume. CONCLUSIONS Dermal-fat graft augmentation gluteoplasty provides a voluminous, natural-feeling, and durable aesthetic result. The procedure should be considered a viable option for patients undergoing abdominoplasty or torsoplasty, especially as more experience is gained. LEVEL OF EVIDENCE 4.

Abstract
No clinical protocols are routinely used to intraoperatively assess surgical margin status during prostate surgery. Instead, margins are evaluated through pathological assessment of the prostate following radical prostatectomy, when it is too late to provide additional surgical intervention. An intraoperative device potentially capable of assessing surgical margin status based on the electrical property contrast between benign and malignant prostate tissue has been developed. Specifically, a microendoscopic electrical impedance tomography (EIT) probe has been constructed to sense and image, at near millimeter resolution, the conductivity contrast within heterogeneous biological tissues with the goal of providing surgeons with real-time assessment of margin pathologies. This device consists of a ring of eight 0.6-mm diameter electrodes embedded in a 5-mm diameter probe tip to enable access through a 12-mm laparoscopic port. Experiments were performed to evaluate the volume of tissue sensed by the probe. The probe was also tested with inclusions in gelatin, as well as on a sample of porcine tissue with clearly defined regions of adipose and muscle. The probe's area of sensitivity consists of a circular area of 9.1 mm(2) and the maximum depth of sensitivity is approximately 1.5 mm. The probe is able to distinguish between high contrast muscle and adipose tissue on a sub-mm scale (∼500 μm). These preliminary results suggest that EIT is possible in a probe designed to fit within a 12-mm laparoscopic access port.

Abstract
Actuality of the problem, consisting of restoration of defects and deformity zones on head and neck, is caused by great quantity of patients, surgical treatment of which constitute important medico-social problem. The flaps, raised from temporal and parietal regions, are considered perspective for replacement of defects and the deformity zones on head and neck. But, for their correct isolation and mobilization it is necessary to know the topographoanatomical peculiarities of superficial temporal artery, localization of which differs, depending on the head form. The methods of isolation and mobilization of angiosomic preauricular, postauricular and fascial temporal-parietal flaps were optimized in the clinic, basing on analysis of results of the investigations performed and computeric modeling of the superficial temporal artery branches.

Abstract
PURPOSE To describe the long-term efficacy of transconjunctival excision of subconjunctival orbital fat prolapse. METHODS Retrospective study of consecutive cases of orbital fat prolapse treated with transconjunctival resection between December 2002 and December 2011. RESULTS Thirty-two eyes of 23 patients (19 males and four females) were included. The lesion was unilateral in 14 and bilateral in nine cases. It was located superotemporally in a majority of cases. Excision was performed by opening the conjunctiva and excising the prolapsing orbital fat. The conjunctival wound was closed with 1-2 interrupted sutures. With an average follow-up of 29 months (range 4-108), a recurrence was seen in three cases. The average time to recurrence was 46 months (range 40-52 months). CONCLUSION Transconjunctival excision is a simple, safe and effective primary surgical procedure to treat subconjunctival fat prolapse. In our series, the recurrence rate was 9%, but no additional surgery was required. As the average time to recurrence was longer than our average follow-up, more patients may develop a recurrence in future.

Abstract
OBJECTIVE To explore the clinical effect of using dorsal two wing-shaped flap to reconstruct finger web for treatment of congenital syndactyly. METHODS This technique has been used in 19 children with congenital syndactyly. At the dorsum, a flap with V-shaped tip and two wing-shaped pedicle were designed and was just sewed up with an anchor-shaped incision at the palm. The web was primarily reconstructed without skin graft at base of fingers. Distal end of fingers were separated by using serrated flap and were closed after removal of fatty tissue. At some cases with tight skin connection. The defect area at lateral and distal end of fingers was closed by small pieces of skin graft. RESULTS All the webs were reconstructed primarily without skin graft at the base of fingers. 7 cases with tight skin connection had small pieces of skin graft at lateral and distal end of fingers. Primary healing was achieved in all cases. After 1 to 6 months of follow-up, both the appearance and function were satisfactory without conspicuous scar. The reconstructed finger webs were in normal depth and width. CONCLUSIONS Primary web space can be achieved by dorsal two wing-shaped flap without skin graft at base of fingers. It is one of the best choices for treatment of congenital syndactyly.

Abstract
OBJECTIVE To investigate the T2 relaxation values of the infrapatellar fat pad (IFP) after arthroscopic surgery. MATERIALS AND METHODS This study was approved by the institutional review board; all individuals signed informed consent. We performed MRI in 16 knees from 8 subjects. Prior to imaging, each subject had unilateral arthroscopic knee surgery and an asymptomatic non-operated contralateral knee. We used a 10-echo multiple-TE fast-spin echo pulse sequence for creation of T2 relaxation time maps. Two musculoskeletal radiologists independently placed regions of interest in the IFP, suprapatellar subcutaneous and deep intermuscular adipose tissue. Qualitative assessments were performed to assess fibrotic changes affecting patellar retinaculum and IFP. Statistical analyses of T2 values determined differences between groups, correlation with time after surgery, and cut-off values to differentiate groups. RESULTS The average time between arthroscopy and imaging was 3.5 ± 0.4 years. IFP of knees with prior surgery had significantly shorter mean T2 values (133 ± 14 ms) compared with control knees (147 ± 8 ms, P = 0.03). There was no significant difference between operated and control knees regarding T2 values of suprapatellar subcutaneous (P = 0.3) or deep intermuscular adipose tissue (P = 0.2). There was no correlation between IFP T2 values and time after surgery (P > 0.2). IFP T2 values ≤ 139 ms had 75 % sensitivity and 88 % specificity in identifying prior arthroscopy. CONCLUSION Shortening of T2 relaxation values is present in IFP chronically after arthroscopic surgery and may be an indicator of adipose tissue fibrosis.
